Halloween // What costumes go with an evil dolls theme? (Other than doll costumes)

My moms doing an isle of the dolls theme for Halloween. I wanna match me and my dogs costumes to it, but I’m not sure what to dress as. I don’t want to just be a haunted doll cause my moms already doing that costume and I want to be a bit different but still kinda on theme, so do y’all have any ideas?
